The Nike Space Hippie 04 Mystic Navy is named after the idea of using materials that are not used or wasted and giving them a second life, just like the Space Hippie movement. The Nike Space Mystic Navy Hippie 04 features a woven texture on the upper and the sole is made from Nike's proprietary ZoomX foam, which is derived from foam scraps collected from the Nike factories. The ZoomX foam is incredibly lightweight and provides excellent cushioning and energy return. The outsole is made from Nike Grind, a material created from recycled rubber. This material is durable and provides excellent traction on a range of surfaces while also reducing carbon footprint. Our experts think that the standout feature of the Nike Space Hippie 04 Mystic Navy is its unique construction. The shoe has a partially translucent upper made from a blend of recycled materials such as recycled plastic bottles, t-shirts, and yarn scraps. The Nike Space Hippie 04 Mystic Navy was released in 2020 for $130.00.
